Set the oven to 220°C / 430°F (regular) or 200°C / 390°F (fan-forced). Lightly coat the baby potatoes in olive oil, season with salt and pepper, and distribute evenly on a baking tray. Roast for 15 minutes to start their cooking process.
As the potatoes bake, combine all rub ingredients in a small bowl until smooth. Generously coat the pork chops on both sides with this mixture, reserving some for later use.
After 15 minutes, remove the tray, stir the potatoes, and shift them toward the edges to make space. Lay the pork chops in the center. Return the tray to the oven and bake for 15 minutes.
Once baked, switch the oven to broil/grill mode on high with the rack about 20cm / 8″ from the element. Flip the pork, apply the reserved rub including the edges, and broil for 7–10 minutes until a sticky, caramelized surface forms.
Extract the tray, brush the pan juices over the chops for added richness and visual appeal, then return it under the broiler for a couple more minutes to intensify the color and glaze.
Serve immediately, spooning over the pan juices and garnishing with chopped parsley if desired.
